[QUOTE="RainyP71, post: 16546961, member: 172042"] Subbed. Op, im trying to do a somewhat similar engine. Sticking to a mild build, with a long block combo to handle 600hp with ease and reliability, but starting out N/A, then swapping a stock pullied eaton I have once I have the time to modify the car to run the heat exchanger and intercooler. After that's running I'll start on my all out Aluminator build. Was flirting with between 10 or 11:1 with e85 as it's available around here, but have not looked at the math yet to see if everything will be in a safe range.
